Abstract
Description
Bridger | Trunk/Bridger amplifiers amplify and reamplify cable |
Amplifier - | signals for transmission through a cable television trunk |
system and out to the distribution system. They provide the | |
interface between the trunk and distribution systems. Also | |
called a bridger or a trunk/bridger amplifier. | |
Cascade - | A serial path extending from an active device. |
CM - | Cable modem. |
CPE - | Customer premises equipment. |
Fork - | The verb “to fork” means the act of one or more instances |
of a segment of code within a script and executing each | |
instance independent of the others. The original script is a | |
“parent” and each instance is a “child.” The parent | |
continues to execute while each child is executing. | |
HFC - | Hybrid Fiber Coax. A network design that employs both |
fiber optic and coaxial cables to deliver cable video and | |
data services. | |
Hub - | The local source of cable services. By way of illustration |
and not as a limitation, a hub may serve 20,000 subscribers. | |
IP Address - | A uniquely addressable identifier associated with network |
or home equipment capable of responding to a ping. | |
Line | An amplifier that reamplifies the signal from the |
extender - | Trunk/Bridger amplifier. Taps that provide the cable |
connections to the homes are installed in the distribution | |
cabling between the Trunk/Bridger amplifiers and the line | |
extenders. | |
Node - | A device that provides an interface between the fiber optic |
and coaxial cable systems of an HFC cable system. Light | |
from a fiber optic cable is converted into an electrical | |
signal suitable for delivery in a coaxial cable system within | |
this device. | |
Ping - | The verb “to ping” means the act of using the ping utility or |
command. The ping utility sends a packet to a device with | |
an IP address and waits for a response. The response is | |
indicative that the ping packet was received by the device | |
and the device is present on the network. The noun “ping” | |
means the request for a response from a network device. | |
Poll - | The verb “poll” means the act of using a utility or |
command by one network device to request data from | |
another network device. | |
STB - | Set top box. |
Tap - | A passive device that divides out small amounts of signal |
for connection to the homes. They typically have 2, 4 or 8 | |
ports for connection of drop cables. | |
